The Rampage Final Stage kit replaces the internal components
that are most likely to fail under increased spring tension with high strength
POM and zinc alloy. All of the corners and edges of the POM components have
been radiused to increase strength and the plunger head has been redesigned for
durability and to reduce the wear on the plunger body. The replacement spring
is rated at 5+ kg and is designed to function as smoothly as the stock spring
while more than doubling the dart’s velocity at the muzzle. The included
plunger head plug is an optional part that should be used if you experience
trouble priming your blaster. The plunger head plug makes up for a loss of draw
length found in some versions of the Rampage shell.

Included in this kit:

POM Plunger Rod

Metal Reinforcement Plate

Metal Trigger Catch

Polished Metal
trigger

5Kg Mainspring

Silicone
grease

O-ring

Trigger and trigger catch springs

Plunger Head Plug (Optional: needed in certain Rampage versions)

*Modifying blaster may wear out or damage
components. Please do so responsibly and at your own risk!

90fps muzzle velocity with up to 70ft range (parallel to ground) 90fps muzzle velocity with up to 80ft range (30 degrees angled to ground)

7 Kg Main Spring:

105fps muzzle velocity with up to 75ft range (parallel to ground) 105fps muzzle velocity with up to 85ft range (30 degrees angled to ground)

I bought this kit as my second upgrade I have done to my nerf blasters. It was a fantastic kit to learn the inner workings of the rampage as it gave me a little trouble (let me clarify, not OMW fault). I had a few problems initially with the metal trigger as it had a tendency to catch and would not release the plunger, so I decided to stay with the plastic stock trigger to save frictional issues. The other minor problem I had was with the plunger rod's inner red housing. The housing kept being sucked out and would get lodged in the tube making the plunger get stuck, I removed that with no major issues to range or power. I did not want to glue it as I feared the glue may increase friction or glob it up. I oddly appreciate all these little intricacies as one of the reasons I bought this was to both upgrade and learn more about how my nerf blasters work.

I purchased this kit for my son's birthday and a nice father/son project in advance of a nerf party. This was my first mod kit experience. The quality and instructions are top notch. A lot of engineering obviously went into the product. Overall the blaster performance is up significantly resulting in longer range, power and accuracy.
